In early August, the early ongrowth of white light, early summer, the weather turned cold, plant growth gradually accelerated, should be chasing 1 leaf fertilizer. It can apply 225-300kg of compound fertilizer per hectare, or 225kg of urea and potassium sulfate, or 15000-22500kg of decomposed organic fertilizer. The fertilizer can be applied to the furrows of ridges and cultivators can be mixed into the ditch and then watered to meet the requirements. The need for leaf growth and increase.
In early September, the temperature dropped to the appropriate temperature for scallion growth, and the light blue stalks entered the peak period of growth, which was the fastest period of yield. At this point, the green onions require the most fertilizer, should be applied to attack the tree fertilizer, the amount of fertilizer should be equal to or slightly more than the first time the amount of fertilizer. After dressing, it can be bred on both sides of the green onion to turn the original ridge back into a furrow, and timely watering can meet the needs of the fast growing onion.
The cool weather from late September to early October is a period when the photosynthetic products of welsh onions are being used to speed up storage and the production of light blue rice is significantly increased. It is also the peak period of fertilizer production before product formation. Should chase big fertilizer 1 time. Generally, 60,000 to 75,000 kilograms of organic fertilizer is applied per hectare, plus 375 kilograms of compound fertilizer or 300 kilograms of each of urea and superphosphate.
After October, because the fertilizer was sufficient, the number of leaves and leaf area had increased to the top, so no additional fertilizer was needed.
